NT QFFICE 2,553,976 I EXTENSION TABLE WITH ADDITIVE LEAF' Herbert F. Lyon, Memphis, Tenn. Application November 13.1948, serial No. 59,834' 1` claim.l (ci. B11-48.)

invention relates to :an extension table, Vand particularly to lan extension table having a tcp member preferably in oneundivided'pieceA and hingedfdropileavesat i-ts ends byt-whichfits length "-maybe increased, ini whichtableprovisionis also 'm'ad'e'k-or the insertion ofl a leaf or leaves bevtweenv the' solid; topv and-l thefdr'o'p leaves.

' The ob'jects'lclfthe inventionliarve:

'To vprovide as an articleAo-fM furniture a .table havinganuninterrupted top together with an ladditiveleafs adapted :for positioning. at the end fief theA tabletop 'an'dmea'ns for supporting the additive leaf' such position to accomplish extension-Pof said table.-

VTo'provide Tan 'extension table of simple and .ecient construction adapted for .practical and fecnoiriicrnanufacture; l To' .provide smooth rand unbroken side rails when. 'the' table is nnextended;

- *Ilo provide an extension table Vand ller leal` in'- which the leaf is housed withinthe table when not in use;

To provide means for efficiently supporting and lining up the filler leaf for use;

v To provideliinge means for lining up the drop leal/estan@ y To provide simple and efficient means for accomplishing the extension of the table and limit'- ing such extension.

The means by which' th'eforegoing' and other' obj ectsare accomplished l'andl'the mannerY of.' their accomplishment will readily be understood from the` following speciiication on reference `to the accompanying. drawings, in which:

Figi-.1` is a side elevation of 'the table over-7* extended-and with. the filler leaf loosely placed.

Fig. 2 is a corresponding plan View; Fig. l3 is a sectional. plan taken on the line and the slide and stop members respectively carried by each.

Fig. Lifis a sectional elevation taken on the line TV1-IV of; Fig. 2.

Fig. 5 is a sectional elevation taken on the line V-V of Fig. 2.

Fig. 6 is a fragmentary sectional elevation taken on the line VIVI of Fig. 5.

Fig. 7 is a sectional elevation of one end of the table taken on the line VII-VII of Fig. 8.

Fig. 8 is a sectional cross elevation of the table taken on the line VIII-VIII of Fig. 7; and

Fig. 9 is a section on the line IX-IX of Fig. 1 showing the hinge attachment of the drop leaf.

Referring now to the drawings in which the -toiill lthe grooves 'IAA and 20A of the complementary side and slide rails is rigidly secured in Il IIIAI of Fig. 1 showing. fragmentary portionsk l o'fthe side rail and complementary slide rail 2 various partsV are indicated by numerals, l i2 is a sol-id table top whichy overliesV and is rigidly secured at its opposite sides to side rails I4, and atV one end to an end rail I6, and is supported by aie'g'l solidly secured to the end rail I6 at *its center. Slide rails 2D are secured at their out-er ends to `Van oppositely disposed end rail A22, the latter end rail also being solidly secured to `and"support-ed by a single leg 214. Inwardly of the -leg thev side rails are additionally secured to `opposite endsY of a cross rail 26 lwhich also is preferably secured to the inner side of the leg Z4. Y Adjacent their innerends the slide rails are V`further securedA to andy braced apart by an aux- 15.

iliary cross rail 21.

The slide rails 20 are disposed vbetween the side rails i4 and in respective sliding con-tact therewith, the contacting `faces of the rails being respectively provided with complementary grooves-IllA and 29A. A block 2S of cross section the groove IAA of' the side rail adjacent its free end, andra similar blockk 3B is secured in the glifoove 2SA of the slide rail at its free end, the `block 28 being slidable in the groove 26A and the block 3S being slidable in the groove MA, the two blocks cooperating to limit extension movement of the sliding rails with respect to the sideV rails. rIhe ends of the-side rails M are provided with halved end portions MB which overlap and hide the ends of the end rail I5, and when the table is not extended also overlap 'and hide the endf'rails 22, presenting a nished and pleasing side appearance.

Hinged to' the opposite end rails i6 and 22, as by hinges `3d, are drop leaves 36 of the table topj which leaves hang downward from the hinges but which may be turned into horizontal position to extend thelength of the table either at one or both ends. When raised the extending portion of the dropends are supported 4by braces 38 of well knowntype.

top of the rail and its hinge pin offset laterally outward beyond the outer face of the rail, and its other half secured to the under surface of the drop leaf, in order that when the drop leaf raised to horizontal the edge 38A. of the drop leaf will be supported by the hinge half and held in underlying contact with the under cut edge IZA of the table top I2 and the top surface of the leaf lined flush with the surface of the table top.

Extending between the cross rail 2l and the end rail 22 is a rod 40, and between the -cross rails 28 and 21 is a second or support rod 42 which is laterally offset from, and below the rod 48. Supported from the rod d by oscillatable brackets Q4 is a filler leaf 46 transversely cut into halves 48A, 56B which are connected by hinges 48 to fold flat together for storage and open out to full length for use, the length of the leaf when opened out for use being identical with the width of the table and its edges under and over cut complementary to the drop leaf and table top edges 36A and IZA (Fig. 9). When folded the filler leaf 48 is turned about the rod 40 into the space between the slide rails 28 and the leaf half 45B supported by the rod 42, the entire leaf being below the level ofthe table top I2.

The table when unextended presents la Smooth unbroken top I2 and side rails M, and the drop leaves 38 may be allowed to hang down and complete a compact and finished table.

Where a longer table is desired one or both the drop leaves 36 may be raised and supported in raised position.

To further lengthen the table the sliding end is pulled out uncovering the filler leaf 46, such action being limited by the blocks 28 and 38 (Fig- 3). The folded filler leaf d8 is raised from the support rod 42 (Fig. 8) and pivotally swung about the rod 40 until the half 46A rests on one of the rails 29, and the other half 46B unfolded to rest on the other of the rails 2B. The two sections are then moved together clamping the ller leaf between the end edge of the top I2, andthe inner edge of the drop leaf. This closing movement brings the end rail 22 into supporting position beneath the outer edge of the ller leaf and the auxiliary rail into supporting position intermediate the width of the leaf and effects a stable support for the leaf. The undercut end IZA of the table top prevents any unforeseen upward bulging of the leaf at the center and substantially insures smooth surface alinement of the top and leaf.

The housing of the leaf insures that it will be available at all times for use 'and substantially insures that no warping and consequent ill fitting such as often occurs when leaves stand around for indefinite periods, will occur.

1t will be understood that @We pedestal legs are shown for purposes of illustration, but that four legs of usual type may be used if so desired.

having undercut end edges, and when It will be understood that two pedestal legs 46 is placed at an end of the table top rather than in the usual manner between sections of such top, andis therefore an additive leaf rather than a filler or insertable leaf.

I claim:

An extension table comprising complementary sections, an additive leaf and hingedly attached drop leaves at the opposite end of said table, each section including an end rail land'supporting leg means; a first of said sections including uninterrupted side rails of length to extend from end rail to end rail, and an uninterrupted top secured to said rails, said top being of width and length to overlie said side rails and said end rails and said table is not extended, completing with said rails a finished table with uninterrupted top, side and end rails; the second of said sections including side rails extending from its said end rail between -and in cooperative telescopic engagement against the inner sides of the side rails of said rst section, and being retractable from said first section to receive said leaf, said leaf being Supportable by the' rails of said second section in contact with the proximate end of said top when said second section is retracted, to extend the length of said table, said drop leaves being hinged each to a proximate end rail, and being each provided with bracing means cooperating with the related said proximate rail for support of the related said drop leaf in raised position; said drop leaves'having their rail proximate edges overcut complementary to the end edges of said top, said insertable leaf havingan overcut side edge complementary to the proximate undercut end of said top, restraining upward displacement of s-aid leaf, the opposite edge of said leaf being undercut for engagement by the proximate edge of the related said raised drop leaf and being restrained against movement endwise of said table by said drop leaf.
